Note: The last digit in the AXE model number denotes heat sink size. See mechanical drawings below.
>xxx4 replaces the Curtis 1204 short heat sink at 6.5” in length (165.1mm)
>xxx5 replaces the Curtis 1205 long heat sink at 8.5” in length (215.9mm)


Model number breakdown, for example the { AXE4834P } is broken down as:

  • AXE – Family name
  • 48 – First two digits = Battery String Voltage (two digits)
  • xx3x – third digit = amperage, 3=300 Amp model
  • xxx4 – fourth digit = Case size small heat-sink
  • “P” model – Denotes Plug Break, “M” denotes Momentary

LED Status Indicator

The LED located on the front of the unit provides status of the units operation and used for troubleshooting.

The LED Blink Codes occur at power up, the number of green blinks indicates the throttle configuration:

  • 1 Green LED flash = 0-5 kohm resistive
  • 2 Green LED flashes = 5K-0 ohm resistive
  • 3 Green LED flashes = 0-5 Volt
  • 4 Green LED flashes = EZ-GO inductive (ITS)
  • 5 Green LED flashes = Yamaha 0-1K ohm resistive
  • 6 Green LED flashes = Taylor-Dunn 6-10.5 Volt
  • 7 Green LED flashes = ClubCar 5k-0 ohms, 3-wire throttle

Normal display status:

  • Solid Green: Controller ready to run
  • Solid Red: Controller in programming mode (using Controller Pro)
  • Solid Yellow: Controller throttle is wide open, controller is supplying max output, and is not in current limit.


Error code display: # of RED blinks indicates any error conditions that might exist:

  • 1 Red = Throttle Position Sensor Over Range. Check for open wires.
  • 2 Red = Under Temperature. Controller below -25C
  • 3 Red = HPD. Throttle hasn’t gone to zero during this power on cycle.
  • 4 Red = Over Temperature. Controller over 95C
  • 5 Red = Not used
  • 6 Red = Battery Under Voltage detected. Battery V < under voltage slider
  • 7 Red = Battery Over Voltage detected. Battery V > over voltage slider
